PHP 4.0 Bug #9718 Updated: Memory leak when passing String values into methods through COM

ID: 9718 Updated by: phanto Reported By: Jason@hspace.net Old-Status: Open Status: Closed Bug Type: COM related Assigned To: Comments: fixed. Previous Comments: --------------------------------------------------------------------------- [2001-03-20 17:59:36] Jason@hspace.net I think that you've fixed the problem. Thanks. --------------------------------------------------------------------------- [2001-03-20 17:44:44] phanto@php.net could you try again with the latest cvs version. i've rewritten a lot. harald --------------------------------------------------------------------------- [2001-03-14 16:58:32] Jason@hspace.net On that note, changing code to below also leaks memory. Variables html_example_test01, etc are declared as public static variables in the COM component. Methods set_html_example_test01() etc set the static variables to the string values passed through the argument. <? Code block sets all public static variables $gbl_obj->set_html_example_test01("Test string #01."); $gbl_obj->set_html_example_test02("Test string #02."); $gbl_obj->set_html_example_test03("Test string #03."); $gbl_obj->set_html_example_test04("Test string #04."); $gbl_obj->set_html_example_test05("Test string #05."); $gbl_obj->set_html_example_test06("Test string #06."); $gbl_obj->set_html_example_test07("Test string #07."); $gbl_obj->set_html_example_test08("Test string #08."); $gbl_obj->set_html_example_test09("Test string #09."); $gbl_obj->set_html_example_test10("Test string #10."); $gbl_obj->set_html_example_test11("Test string #11."); $gbl_obj->set_html_example_test12("Test string #12."); $gbl_obj->set_html_example_test13("Test string #13."); $gbl_obj->set_html_example_test14("Test string #14."); $gbl_obj->set_html_example_test15("Test string #15."); $gbl_obj->set_html_example_test16("Test string #16."); $gbl_obj->set_html_example_test17("Test string #17."); $gbl_obj->set_html_example_test18("Test string #18."); $gbl_obj->set_html_example_test19("Test string #19."); $gbl_obj->set_html_example_test20("Test string #20."); // script does not leak memory when I remove this code block ?> I hope this clarifies the problem. Earlier examples weren't right as I have done lots of code with COM which work without leaking memory. --------------------------------------------------------------------------- [2001-03-14 16:46:18] Jason@hspace.net Disregard my previous example with the classes. I've just tried a test without using classes and it still leaks memory. Consider example below instead, thanks: Code block sets multiple public variables in COM object. In below example, $gbl_obj is an instance of the COM object in the global scope of the PHP page. The public variables are defined as html_example_test01, html_example_test02, html_example_test03, etc. etc. My code block sets over twenty public variables in the COM object. <? Code block sets all public variables in COM object $gbl_obj->html_example_test01 = "Test string #01."; $gbl_obj->html_example_test02 = "Test string #02."; $gbl_obj->html_example_test03 = "Test string #03."; $gbl_obj->html_example_test04 = "Test string #04."; $gbl_obj->html_example_test05 = "Test string #05."; $gbl_obj->html_example_test06 = "Test string #06."; $gbl_obj->html_example_test07 = "Test string #07."; $gbl_obj->html_example_test08 = "Test string #08."; $gbl_obj->html_example_test09 = "Test string #09."; $gbl_obj->html_example_test10 = "Test string #10."; $gbl_obj->html_example_test11 = "Test string #11."; $gbl_obj->html_example_test12 = "Test string #12."; $gbl_obj->html_example_test13 = "Test string #13."; $gbl_obj->html_example_test14 = "Test string #14."; $gbl_obj->html_example_test15 = "Test string #15."; $gbl_obj->html_example_test16 = "Test string #16."; $gbl_obj->html_example_test17 = "Test string #17."; $gbl_obj->html_example_test18 = "Test string #18."; $gbl_obj->html_example_test19 = "Test string #19."; $gbl_obj->html_example_test20 = "Test string #20."; // script does not leak memory when I remove this code block ?> I am using long variable names like html_example_test01 --------------------------------------------------------------------------- [2001-03-14 09:06:35] Jason@hspace.net Corrections to bug report. Ignore previous example, check with the below example instead. I'm actually assigning values from inside a child class in PHP and accessing the COM object in the base class. eg: <?php class Child { function Child () { Base::instance(); $this->obj->testvar = "This is a test string."; } } class Base { function instance() { $this->obj = new COM("MyObject.MyObject"); } } ?> / Leaks memory when I assign a string to a public variable (testvar) of COM object (obj) from an instance of Child. Disregard my previous examples as I've tested my COM object with a simple string passed as argument to method and it did not leak memory. I think the above memory leak has something to do with PHP's handling of Object Oriented Programming... --------------------------------------------------------------------------- The remainder of the comments for this report are too long.
